Tetryl is a nitramine booster explosive, though its use has been largely superseded by RDX. Tetryl is a sensitive secondary high explosive used as a booster, a small charge placed next to the detonator in order to propagate detonation into the main explosive charge. ==Chemical properties== Tetryl is a yellow crystalline solid powder material, practically insoluble in water but soluble in acetone, benzene and other solvents. When tetryl is heated, it first melts, then decomposes and explodes. It burns readily and is more easily detonated than ammonium picrate〔http://www.globalsecurity.org/military/systems/munitions/explosives-booster.htm〕 or TNT, being about as sensitive as picric acid. It is detonated by friction, shock, or spark. It remains stable at all temperatures which may be encountered in storage. It is generally used in the form of pressed pellets, and has been approved as the standard bursting charge for small-caliber projectiles, since it gives much better fragmentation than TNT. It also has greater brisance than any other military high explosive and has an explosive velocity of 23,600–23,900 feet per second (7200–7300 m/s). Tetryl is the basis for the service tetryl blasting caps necessary for positive detonation of TNT. A mixture of mercury fulminate and potassium chlorate is included in the cap to ensure detonation of tetryl.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「tetryl」の詳細全文を読む スポンサード リンク
